Background: Mandible is the strongest bone in the face region required for the process of mastication. The inferior alveolar nerve travels inside the bone in the mandibular canal to supply the lower teeth. The measurement of various parameters of mandible allows the proper localization of nerve for anaesthetic block. Also, the ratios between factors assists during surgeries. Aim and objective: To study the variations of Various parameters of the mandible. Material and method: The study was conducted on 122 adult dry human mandibles in the Department of Anatomy, Index Medical College Hospital & Research Centre, Indore. The different Parameters was measured using vernier callipers. Results:The gonial angle of the male mandible was between 116° and 141° with an average of 126.41°. The average gonial angle of the female mandible is 137.5 °. The mandibular angle was less than 162 °in men and > 110 °in women.The maximum angle of the mandible was 134 °, which was correctly estimated in 84 % of men and 67 % of women.The mean mandibular angle values for men and women were significantly different (p < 0.001) for the mandible. Conclusion: Male mandible shows triangular type commonly. Among the various types of coronoid processes, triangular process is the most prevalent.
